TIre pressure during towing vs not towing

I would leave it alone. Once you are settled somewhere and staying for several weeks you may want to reduce the air pressure for a better ride, but the change isn't that significant. The few miles you will put on while sightseeing etc aren't going to have any effect on tire wear if the pressure is a bit high...I carry a small 110 compressor as well as a 12 volt. The 12 volt will take forever to blow up a tire, if it doesn't burn up first. The exception would be one of the more expensive 12 volt set ups. My last truck had 265/75/17s load range E. They recommended 45 psi for a light load and 79 psi for heavy. I ran 80 psi in the rear when towing and 70 in the front...

I think I would be very caution running an 80 PSI tire in the mid 40s. With Radial Tires, you must keep enough pressure in them to keep the bead seated. If you run too low a pressure and go into a corner hard you have the possibility of roll the tire right off the rim.

What does manufacturer recommends? Do they expect us to keep the air pressure the same all the time (hence compromising the unloaded ride somewhat) or use two different pressure levels?

So I have to assume you are talking about rear tires on a TV. I lower mine to 42-44 empty when they are going to be that way for weeks. My truck drives like do-do with 75-80 lbs inflation when empty.
I run 57-59 in the front all the time, as that weight does not change. Chris

I daily drive my TV, running lower pressure when unloaded saves tire wear and makes for a smother ride.

Yes I am talking about the rear wheels, pulling a 5th wheel.

Ok, so some of you DO adjust the air pressure... For those who do adjust, how do you increase the pressure? Do you use a portable air compressor hooked up to the cigarette 12V power?

When we eventually go full-timing, we will drive a 1t dually. Will dually behave ok not towing when the tires are max pressured? We do expect to drive every day and sometimes 100-200 miles at a time when not towing.

I run max pressure all the time....no worries.

Please direct us to this thread. Since this is in 5th wheels we're all (well, most of us) assuming you mean the 5th wheel tires.

If I am just staying for a couple of days I just leave it. Longer than that I drop pressure cause my truck rides like tank.

I guess because I don't know any better... :)

I just read from another thread that this needs to be done and this is the first time I read about this so....

Ok, so based on your feedback so far, there's NO NEED to adjust air pressure?
